Painting in Stellenberg

Stellenberg properties tend to sit on established stands with substantial mature trees, and that shade creates a very specific painting problem. South and south-east facing walls that sit under tree canopy stay damp for long stretches through winter, and the green or black staining that appears on them is algae and mould growth, not dirt.

That distinction matters because algae cannot be painted over. The spores survive under the new coat and grow back through it, usually within a single wet season. The correct sequence is a fungicidal wash, left on for the full dwell time the manufacturer specifies, then rinsed, then dried, then painted with a topcoat carrying a fungicide. A painter who plans to jet-wash the wall and paint it the same afternoon is going to give you the same problem back next winter.

The other consequence of mature trees is gutters. Leaf litter blocks them, water backs up, and the overflow runs down the wall and keeps a permanent damp strip that no paint will survive. Fixing the gutter is part of the paint job whether or not the painter mentions it.

What Painting Costs in Stellenberg

Guide ranges for Stellenberg. The fungicidal treatment lines are the ones that separate a quote that lasts from one that does not.

Job	Guide price
Interior, 3-bedroom home	R18 000 - R28 000
Exterior, single storey	R26 000 - R42 000
Fungicidal wash and treatment, per m²	R25 - R48
Algae removal and recoat, shaded walls, per m²	R85 - R135
Gutter and fascia repaint, per linear metre	R110 - R190
Roof repaint including moss removal, per m²	R105 - R165
Plain wall area, two coats, per m²	R52 - R80

Fungicidal treatment at R25 to R48 per square metre is one of the highest-value lines on a Stellenberg quote. Leaving it off saves a few thousand rand and costs you the shaded walls within two winters.

Timing Around the Shade in Stellenberg

The general window is September to April, but on this side the timing needs to allow for shaded walls drying more slowly than sunny ones. A south wall under tree canopy can still be holding moisture in October when the north wall has been bone dry for weeks.

For that reason, late summer - February through April - is often the better slot for shaded elevations specifically. They have had the full dry season to give up their moisture, and the fungicidal treatment works far better on a genuinely dry substrate.

Sunny elevations can go earlier, from September. There is nothing wrong with painting the house in two phases if that is what the walls need.

Moss and algae on roofs is worth treating at the start of the dry season, around October, so the treatment has months of dry weather to work before the next winter.

Interiors are unaffected and are ideal winter work.

Treating and Coating Shaded Walls

Surface	Recommended system
Algae or mould-affected walls	A proper fungicidal wash applied and left for the full dwell time - typically 20 to 30 minutes - then rinsed and dried completely. Rushing this step is the single most common cause of regrowth.
Exterior topcoat on shaded elevations	Plascon Wall & All or Dulux Weatherguard, both of which contain a fungicide in the film. An additional fungicidal additive can be mixed in for badly affected walls.
Sunny elevations	The same product family, so the finish matches, but you will need less preparation and it will last longer on these walls.
Roofs with moss	Treat with a moss killer, allow it to work, then remove the dead growth with low pressure before sealing and coating. Scrubbing live moss off just spreads it.
Timber fascia and barge boards	Where these have gone soft, replacement beats painting. Painted rot is still rot, and it will take the new paint with it.
Interior walls in shaded rooms	Rooms on the south side with poor ventilation get condensation mould in corners and behind furniture. Improve airflow, and use a washable interior with mould resistance in bathrooms and shaded bedrooms.

Before You Repaint in Stellenberg

Identify whether the staining is dirt or growth. Green and black staining on a shaded wall is almost always algae or mould
Insist the fungicidal wash gets its full dwell time before rinsing - this is where quotes quietly cut corners
Clear and repair the gutters before painting, and cut back overhanging branches touching the walls
Let shaded walls dry properly. If in doubt, they get done in late summer rather than early spring
Check that the specified topcoat actually contains a fungicide, and ask about an additive for the worst walls
Look at timber fascias and barge boards for soft spots - replace rather than paint over them

Stellenberg Painting Questions

Why does the green come back on my shaded wall?

Because the algae was painted over rather than killed. The spores survive under the coating and grow back through, usually within one wet season. It needs a fungicidal wash with the full dwell time, a proper rinse, complete drying, and then a topcoat containing a fungicide.

How much does treating algae add to a quote?

About R25 to R48 per square metre for the fungicidal wash and treatment, or R85 to R135 per square metre if the affected walls need full removal and recoating. On a shaded elevation it is the best value item on the whole quote.

Should I paint the shaded walls at a different time of year?

Often, yes. Shaded walls under tree canopy hold moisture much longer, so late summer - February to April - gives a better result on those elevations than early spring. There is no problem doing the house in two phases.

Do gutters really affect the paint?

Very much. A blocked gutter overflowing down a wall keeps a permanent damp strip, and no exterior paint survives constant wetting. Clearing and repairing gutters, and cutting back branches, should happen before painting, not after.

What about mould inside the house?

Interior mould in corners and behind furniture on south-facing walls is condensation, not rising damp. It is fixed with ventilation and heating rather than paint, although a mould-resistant washable interior helps in bathrooms and shaded rooms.
